mixed germ cell tumor

Mixed germ cell tumord are much more common in the testis (33 vs < 1%).

Almost any admixture is seen in the testis, many with roughly equal frequency, whereas in the ovary various combinations of yolk sac tumor, dysgerminoma, and teratoma account for the great majority.

Finally, in the testis a random admixture of elements is typical, a more zonal distribution of two or more elements being more usual in the ovary, without implying that the opposite cannot be seen on occasion.
